The beings on Zeta Reticuli are the future selves granted, several million years into the future of the beings on Earth right now. On the soul level, this had to do with your evolution to become more, and to be more established benevolently on a creative level. By the time your souls become those Zeta Reticulian beings several million years into the future, you will be able to interact with all life in the most benevolent way while being strongly intellectual and scientific.
In this way, your science will have a complete balance with a heart and soul. This is one of the greatest aspects of significance between you and the Zeta Reticulian beings as of this time. So to them you are their past lives that’s why they’re so fascinated with you but for you, when you interact with these beings, you are truly meeting, in many senses, your future.
